effects of experimental lead exposure on testis of the chestnut capped blackbird chrysomus ruficapillus.	lead (pb) effects on testis histology, as well as sperm quality and oxidative status were evaluated in male chestnut capped blackbird (chrysomus ruficapillus). wild blackbirds were captured, immediately sampled (field group) or kept in captivity and treated with a single intraperitoneal injection of saline solution (control) or saline solution with pb acetate (50 or 100 mg/kg pb). seven days after injection, whole blood, ductus deferens and testis samples were collected. increased pb concentrati ...	2018	29383385
frequency of zoonotic bacteria among illegally traded wild birds in rio de janeiro.	the illegal wildlife trade may increase the risk of infectious disease transmission, and it may not only cause disease outbreaks in humans but also threaten livestock, native wild populations, and ecosystems' health. bird species may act as carriers in the transmission of enteric pathogens. however, epidemiological studies on zoonotic bacteria in wild birds are rare in brazil. from march 2011 to march 2012, we investigated the frequency of enterobacteriaceae in cloacal swab samples from 109 bird ...	2016	27528081
characteristics of salmonella spp. isolated from wild birds confiscated in illegal trade markets, rio de janeiro, brazil.	the prevalence of salmonella spp. was investigated in 109 wild birds poached in the illegal wildlife trade in rio de janeiro; most of them are passerines from thraupidae family and three from psittacidae. one strain of salmonella ser. typhimurium and two strains of salmonella ser. panama were isolated from passerine species and all of them showed resistance to multiple antimicrobial drugs, like ampicillin, ceftriaxone, ceftiofur, tetracycline, gentamicin, nalidixic acid, ciprofloxacin, and enrof ...	2016	26881216
spatial patterns of shiny cowbird brood parasitism on chestnut-capped blackbirds	shiny cowbirds, molothrus bonariensisparasitized a high frequency (average 48%) of nests in five colonies of chestnut-capped blackbirds, agelaius ruficapillusin argentina. two distinct egg morphs occurred, spotted and immaculate white eggs, as well as a few very lightly spotted intermediate eggs. the clear differences between morphs, combined with considerable variation in spotting pattern between spotted morph eggs, made it possible to visually match eggs into groups that were probably laid by ...	1997	9344445
